Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Clams
Provide the main protein and briny, seafood flavor of the soup.
Butter
Adds fat and richness, and carries flavor from the aromatics.
Onion
Softens and adds savory sweetness as the base of the soup.
Celery
Adds a mild, vegetal crunch and aromatic depth to the base.
Milk
Adds creaminess and a smooth, rich body to the broth.

The step that matters

Heat through after adding milk. Milk can curdle or scorch if it is boiled hard. Adding it at the end and warming it gently keeps the soup smooth and creamy.

Swap the celery

How well each one fits the dish's main ingredients (clam, butter, onion, milk, pepper):

  1. Parsleyfits better
  2. Garlicfits better
  3. Thymefits about as well
  4. Celerythe original

Fit is the average pairing score against clam, butter, onion, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
